Résumé

Le sulfocyanate d'ammonium et l'aldéhyde formique, formés probablement au cours de l'évolution géochimique, fournissent les structures ressemblant à des cellules. La formation des ces structures, sous des conditions variables de concentration, est catalysée par les irradations UV. Ces formes protocellulaires expulsent leurs contenus vacuolaires et absorbent des matières colorantes. La transition de l'évolution géochimique aux protocellules semble être une étape admissible selon le résultat de nos expériences.
